A Film Bulk Acoustic Resonator-Based Sensor with AlN Piezoelectric Material for Detecting Ethanol and Acetone

<div>The figure for influence of gate voltage change on the resonance frequency shift value during ethanol experiment. The black curve <i>f</i><sub>1</sub> stands for the resonance frequency before ethanol addition, the red curve <i>f</i><sub>2</sub> stands for the resonance frequency after ethanol addition.</div>
